Description

撮像装置Imaging device
　本発明は撮像装置に関し、特に、３Ｄコンバージョンレンズを取り付け可能な撮像装置に関する。 The present invention relates to an imaging device, and more particularly to an imaging device to which a 3D conversion lens can be attached.
　特許文献１は、３Ｄアダプタ（立体画像撮像用カメラレンズアダプタ）と、そのアダプタを取り付け可能な撮像装置とを開示している。この撮像装置は、取り付けられた３Ｄアダプタを光軸を中心として回転させることにより、３Ｄアダプタの取り付け状態を調整できる。この撮像装置においては、３Ｄアダプタの取り付け状態を調整する際、スリットの入ったアダプタキャップを３Ｄアダプタに取り付けて調整を行うように構成されている。 Patent Document 1 discloses a 3D adapter (stereoscopic image capturing camera lens adapter) and an imaging device to which the adapter can be attached. This imaging apparatus can adjust the attachment state of the 3D adapter by rotating the attached 3D adapter around the optical axis. In this imaging apparatus, when adjusting the attachment state of the 3D adapter, the adapter cap having a slit is attached to the 3D adapter for adjustment.
　この状態で被写体像を撮像することにより、使用者は、３Ｄアダプタが撮像装置に対して光軸を中心としてどれだけ回転した状態にあるかを、撮像した像の回転状態により認識できる。 By capturing the subject image in this state, the user can recognize how much the 3D adapter is rotated about the optical axis with respect to the image capturing apparatus based on the rotation state of the captured image.
特開２００３－５０４３８号公報JP 2003-50438 A
　上記特許文献１に開示されている撮像装置では、左目用画像及び右目用画像の撮像素子上での結像位置を調整する際、左目用画像と右目用画像が横方向に並べられた状態となっているので、両画像の垂直方向の位置ずれを精度よく認識しにくい。また、特許文献１の３Ｄアダプタでは、その構造上、左目用画像及び右目用画像の撮像素子上での結像位置を調整する際、左目用画像及び右目用画像の両方が同時に反対方向に動くため、微妙な調整が困難である。このように、特許文献１の撮像装置では、３Ｄアダプタの取り付け状態の精度のよい調整は困難である。 In the imaging device disclosed in Patent Document 1, when adjusting the imaging positions of the left-eye image and the right-eye image on the imaging device, the left-eye image and the right-eye image are arranged in the horizontal direction. Therefore, it is difficult to accurately recognize the positional deviation between the two images in the vertical direction. In addition, in the 3D adapter disclosed in Patent Document 1, when adjusting the imaging position of the left-eye image and the right-eye image on the imaging device, both the left-eye image and the right-eye image simultaneously move in opposite directions. Therefore, fine adjustment is difficult. As described above, in the imaging apparatus disclosed in Patent Document 1, it is difficult to accurately adjust the attachment state of the 3D adapter.
　本発明は、３Ｄアダプタの取り付け状態の調整を高精度に行うことができる撮像装置を提供することを目的とする。 An object of the present invention is to provide an imaging device capable of adjusting the attachment state of the 3D adapter with high accuracy.
　第１の態様の撮像装置は、左目用の画像を形成するための光と右目用の画像を形成するための光とを集光可能な光学系を有する３Ｄアダプタを接続可能であり、光学系の調整を行うための調整モードに設定可能な撮像装置であって、３Ｄアダプタを介して集光された光に基づいて形成された画像を撮像する撮像手段と、撮像手段により撮像された画像を表示する表示手段と、を備え、表示手段は、自装置が調整モードに設定されている際、撮像手段により撮像された左目用の画像と右目用の画像とを重畳して表示する。 The imaging device according to the first aspect is capable of connecting a 3D adapter having an optical system capable of condensing light for forming an image for the left eye and light for forming an image for the right eye. An imaging device that can be set to an adjustment mode for performing the adjustment of the imaging device, the imaging unit that captures an image formed based on the light collected through the 3D adapter, and the image captured by the imaging unit Display means for displaying, and when the device is set to the adjustment mode, the display means displays the left-eye image and the right-eye image captured by the imaging means in a superimposed manner.
　第２の態様の撮像装置は、左目用の画像を形成するための光と右目用の画像を形成するための光とを集光可能な光学系を有する３Ｄアダプタを接続可能であり、光学系の調整を行う調整モードに設定可能な撮像装置であって、３Ｄアダプタを介して集光された光に基づいて形成された画像を撮像する撮像手段と、を備え、調整モードには、左目用の画像、及び右目用の画像の何れか一方の画像が形成される位置を調整するための第１のモードと、第１のモードにおいて調整された一方の画像が形成される垂直方向の位置に対して、他方の画像が形成される垂直方向の位置を揃えるための第２のモードと、が含まれる。 The imaging device of the second aspect can connect a 3D adapter having an optical system capable of condensing light for forming an image for the left eye and light for forming an image for the right eye. An imaging device that can be set to an adjustment mode for adjusting the image, and an imaging unit that captures an image formed on the basis of the light condensed through the 3D adapter. The first mode for adjusting the position where one of the image for the right eye and the image for the right eye is formed, and the position in the vertical direction where the one image adjusted in the first mode is formed On the other hand, a second mode for aligning the vertical position where the other image is formed is included.
　第１の態様の撮像装置によれば、３Ｄアダプタの取り付け状態の調整時、撮像手段により撮像された左目用の画像と右目用の画像とが重畳して表示されるので、調整に際し、左目用の画像の結像位置と右目用の画像の結像位置のずれを使用者が認識しやすい。したがって、３Ｄアダプタの取り付け状態の調整を高精度に行うことができる。 According to the imaging device of the first aspect, when adjusting the attachment state of the 3D adapter, the image for the left eye and the image for the right eye captured by the imaging unit are displayed in a superimposed manner. It is easy for the user to recognize the difference between the image forming position of the image for the right eye and the image forming position for the image for the right eye. Therefore, the attachment state of the 3D adapter can be adjusted with high accuracy.
　第２の態様の撮像装置によれば、３Ｄアダプタの取り付け状態の調整時、左目用の画像と右目用の画像の両方について垂直方向の位置を個別に調整できる。したがって、３Ｄアダプタの取り付け状態の調整を高精度に行うことができる。 According to the imaging device of the second aspect, when adjusting the attachment state of the 3D adapter, the position in the vertical direction can be individually adjusted for both the left-eye image and the right-eye image. Therefore, the attachment state of the 3D adapter can be adjusted with high accuracy.

FIG. 1 is a perspective view showing a state in which a 3D conversion lens 500 is attached to the digital video camera 100. FIG. 2 is a perspective view showing a state in which the 3D conversion lens 500 is removed from the digital video camera 100.
　図１に示すように、デジタルビデオカメラ１００は、３Ｄコンバージョンレンズ５００を取り付けるための取付部６４０を有している。取付部６４０は、内側に雌ネジを有している。一方、３Ｄコンバージョンレンズ５００は、取付部６４０が有する雌ネジに係合する雄ネジを有している。使用者は、３Ｄコンバージョンレンズ５００が有する雄ネジを取付部６４０が有する雌ネジに係合させることで、３Ｄコンバージョンレンズ５００をデジタルビデオカメラ１００に取り付けることができる。なお、デジタルビデオカメラ１００は、３Ｄコンバージョンレンズ５００が取り付けられたことを検出スイッチ８００（後述する図８参照）により磁気的に検出できる。 As shown in FIG. 1, the digital video camera 100 has a mounting portion 640 for mounting the 3D conversion lens 500. The attachment portion 640 has a female screw inside. On the other hand, the 3D conversion lens 500 has a male screw that engages with a female screw included in the mounting portion 640. The user can attach the 3D conversion lens 500 to the digital video camera 100 by engaging the male screw of the 3D conversion lens 500 with the female screw of the attachment portion 640. The digital video camera 100 can magnetically detect that the 3D conversion lens 500 is attached by a detection switch 800 (see FIG. 8 described later).
　図３は、３Ｄコンバージョンレンズ５００の光学系５０１及びデジタルビデオカメラ１００の光学系１０１の構成を説明した図である。３Ｄコンバージョンレンズ５００の光学系５０１は、３Ｄ（three dimensions）画像における右目用の像を形成するための光を導入する右目用レンズ６００と、左目用の像を形成するための光を導入する左目用レンズ６２０と、右目用レンズ６００及び左目用レンズ６２０に導入された光をデジタルビデオカメラ１００の光学系１０１に導くための左目用と右目用とが一体化された共用レンズ６１０とを有する。３Ｄコンバージョンレンズ５００の右目用レンズ６００及び左目用レンズ６２０に入射した光は、それぞれ共用レンズ６１０を介してデジタルビデオカメラ１００の光学系１０１に導入され、デジタルビデオカメラ１００のＣＣＤイメージセンサー１８０（後述する図８参照）に、例えば図４に示すようなサイドバイサイド形式の画像として結像される。右目用レンズ６００及び左目用レンズ６２０は、３Ｄコンバージョンレンズ５００内で個別に上下左右に（光軸に対して垂直な方向に）移動可能に構成されている。 FIG. 3 is a diagram illustrating the configuration of the optical system 501 of the 3D conversion lens 500 and the optical system 101 of the digital video camera 100. The optical system 501 of the 3D conversion lens 500 includes a right-eye lens 600 that introduces light for forming an image for the right eye in a 3D (three-dimensions) image, and a left-eye that introduces light for forming an image for the left eye. And a common lens 610 in which the left eye and the right eye for guiding the light introduced into the right eye lens 600 and the left eye lens 620 to the optical system 101 of the digital video camera 100 are integrated. Light incident on the right-eye lens 600 and the left-eye lens 620 of the 3D conversion lens 500 is introduced into the optical system 101 of the digital video camera 100 via the common lens 610, and the CCD image sensor 180 (described later) of the digital video camera 100. For example, the image is formed as a side-by-side image as shown in FIG. The right-eye lens 600 and the left-eye lens 620 are configured to be individually movable up and down and left and right (in a direction perpendicular to the optical axis) within the 3D conversion lens 500.

FIG. 5 is a top view of the inside of the adjustment mechanism storage unit 530 as viewed from above with the adjustment mechanism storage unit 530 opened. In the adjustment mechanism storage unit 530, a horizontal adjustment dial 540, a first vertical adjustment dial 550, and a second vertical adjustment dial 560 are accommodated. The horizontal adjustment dial 540 is a dial for adjusting the horizontal position of the right-eye lens 600 and the left-eye lens 620.

Configuration of Lens Cap In the present embodiment, the lens cap 570 can be attached to the 3D conversion lens 500. In particular, the lens cap 570 makes it possible to adjust the optical system 501 of the 3D conversion lens 500 while being attached to the 3D conversion lens 500. Hereinafter, the lens cap 570 will be described with reference to FIGS. The lens cap 570 can be attached to the lens cap attachment portion 520. FIG. 6A is a perspective view showing a state in which the lens cap 570 is viewed from the inner surface side. FIG. 6B is a perspective view showing a state in which the lens cap 570 is viewed from the outer surface side. FIG. 7 is a schematic diagram showing the configuration of the lens cap 570 as viewed from the surface facing the lens cap mounting portion 520 when the lens cap 570 is mounted on the lens cap mounting portion 520.
　レンズキャップ５７０の内面には、３Ｄコンバージョンレンズ５００に対する取り付け位置を規定するとともに、レンズキャップ５７０の３Ｄコンバージョンレンズ５００に対する回転を防止するための構造が設けられている。具体的には、レンズキャップ５７０の内面の左右には突起６８０が形成されている。また、３Ｄコンバージョンレンズ５００の先端部外周の左右には、図１に示すように、溝６７０が設けられている。そして、レンズキャップ５７０を３Ｄコンバージョンレンズ５００に取り付けるときに、レンズキャップ５７０の突起６８０と３Ｄコンバージョンレンズ５００の溝６７０とを係合させる。これにより、レンズキャップ５７０の３Ｄコンバージョンレンズ５００に対する取り付け位置が規定されるとともに、レンズキャップ５７０の３Ｄコンバージョンレンズ５００に対する回転を防止することができる。 The inner surface of the lens cap 570 is provided with a structure for defining a mounting position with respect to the 3D conversion lens 500 and preventing the rotation of the lens cap 570 with respect to the 3D conversion lens 500. Specifically, protrusions 680 are formed on the left and right sides of the inner surface of the lens cap 570. Further, as shown in FIG. 1, grooves 670 are provided on the left and right sides of the outer periphery of the tip of the 3D conversion lens 500. Then, when the lens cap 570 is attached to the 3D conversion lens 500, the protrusion 680 of the lens cap 570 and the groove 670 of the 3D conversion lens 500 are engaged. Accordingly, the mounting position of the lens cap 570 with respect to the 3D conversion lens 500 is defined, and the rotation of the lens cap 570 with respect to the 3D conversion lens 500 can be prevented.
　レンズキャップ５７０には、図６（ａ）、図７に示すようなパターンが付されている。具体的には、レンズキャップ５７０には、水平方向に延びる直線からなる基準線５８０が付されている。また、レンズキャップ５７０には、基準線５８０に線対称に配置された２つの三角形からなるパターン５９０が付されている。また、このパターン５９０は、基準線５８０の中点を中心として左右対称に配置されている。領域６１０は、光を透過する樹脂で構成されている。従って、レンズキャップ５７０をレンズキャップ取付部５２０に取り付けた状態で、デジタルビデオカメラ１００は、図７に示す模様を撮像できる。パターン５９０は、２つの三角形からなるパターンであるので、斜め方向に延びる線を有している。そのため、パターン５９０は、コントラストＡＦ方式において合焦させやすいというメリットがある。なお、斜め方向に延びる線を有していれば、パターンは三角形である必要はない。 The lens cap 570 is provided with a pattern as shown in FIGS. Specifically, a reference line 580 made of a straight line extending in the horizontal direction is attached to the lens cap 570. The lens cap 570 is provided with a pattern 590 formed of two triangles arranged symmetrically with respect to the reference line 580. The pattern 590 is arranged symmetrically about the midpoint of the reference line 580. The region 610 is made of a resin that transmits light. Therefore, the digital video camera 100 can capture the pattern shown in FIG. 7 with the lens cap 570 attached to the lens cap attaching portion 520. Since the pattern 590 is a pattern composed of two triangles, it has a line extending in an oblique direction. Therefore, the pattern 590 has an advantage that it can be easily focused in the contrast AF method. Note that the pattern need not be triangular as long as it has lines extending obliquely.

　使用者により３Ｄコンバージョンレンズ５００がデジタルビデオカメラ１００に取り付けられると、コントローラー２１０は、検出スイッチ８００からの検出信号に基づき、３Ｄコンバージョンレンズ５００が取り付けられたことを検出する（Ｓ１００）。３Ｄコンバージョンレンズ５００が取り付けられたことを検出すると、コントローラー２１０は、図１０に示すメッセージを表示するよう液晶モニタ２７０を制御する（Ｓ１１０）。具体的には、「３Ｄ撮影の初期設定を行っています。」とのメッセージを表示する。また、液晶モニタ２７０にメッセージを表示させるのに併せて、コントローラー２１０は、３Ｄモードにおける初期設定を開始するようデジタルビデオカメラ１００を制御する（Ｓ１１０）。具体的には、コントローラー２１０は、初期設定として、ズームレンズ１１０を望遠端に移動させたり、画像処理の方法を２Ｄ画像の撮影モードとは異なる方法にするよう設定したりする。なお、図１０に表示したメッセージは一例である。メッセージの内容は、同様の主旨である限り異なる内容でも構わない。図１１、図１２、図１４においても同様である。 When the 3D conversion lens 500 is attached to the digital video camera 100 by the user, the controller 210 detects that the 3D conversion lens 500 is attached based on the detection signal from the detection switch 800 (S100). When detecting that the 3D conversion lens 500 is attached, the controller 210 controls the liquid crystal monitor 270 to display the message shown in FIG. 10 (S110). Specifically, the message “Initial setting for 3D shooting” is displayed. Further, in conjunction with displaying the message on the liquid crystal monitor 270, the controller 210 controls the digital video camera 100 to start the initial setting in the 3D mode (S110). Specifically, as an initial setting, the controller 210 moves the zoom lens 110 to the telephoto end, or sets the image processing method to be different from the 2D image shooting mode. The message displayed in FIG. 10 is an example. The content of the message may be different as long as it has the same purpose. The same applies to FIGS. 11, 12, and 14.
　初期設定が完了すると、コントローラー２１０は、図１１に示すメッセージを表示するよう液晶モニタ２７０を制御する（Ｓ１２０）。具体的には、コントローラー２１０は、例えば「３Ｄコンバージョンレンズ５００の調整をしますか？　調整する場合にはレンズキャップを取り付けてください」というように、３Ｄコンバージョンレンズ５００の位置調整を行うかを問合せて、調整する場合にはレンズキャップを取り付けるよう促すメッセージを表示する。また、コントローラー２１０は、図１１に示すようなＯＳＤを表示するよう液晶モニタ２７０を制御する。具体的には、コントローラー２１０は、水平方向基準線９１０及び垂直方向基準線９００を表示するよう液晶モニタ２７０を制御する。また、コントローラー２１０は、使用者による操作を受け付けるための「調整」を示すＯＳＤ９２０、及び「終了」を示すＯＳＤ９３０を表示するよう液晶モニタ２７０を制御する。 When the initial setting is completed, the controller 210 controls the liquid crystal monitor 270 to display the message shown in FIG. 11 (S120). Specifically, the controller 210 inquires whether to adjust the position of the 3D conversion lens 500, for example, “Do you want to adjust the 3D conversion lens 500? Please attach the lens cap when adjusting.” When adjusting, a message prompting you to attach the lens cap is displayed. Further, the controller 210 controls the liquid crystal monitor 270 to display the OSD as shown in FIG. Specifically, the controller 210 controls the liquid crystal monitor 270 to display the horizontal reference line 910 and the vertical reference line 900. Further, the controller 210 controls the liquid crystal monitor 270 to display an OSD 920 indicating “adjustment” and an OSD 930 indicating “end” for accepting an operation by the user.
　図１１に示される画像を表示するよう液晶モニタ２７０を制御すると、コントローラー２１０は、使用者により「調整」を示すＯＳＤ９２０がタッチされるか、「終了」を示すＯＳＤ９３０がタッチされるまで待機する（Ｓ１３０）。 When the liquid crystal monitor 270 is controlled to display the image shown in FIG. 11, the controller 210 waits until the user touches the OSD 920 indicating “adjustment” or the OSD 930 indicating “end” (see FIG. 11). S130).
　使用者により「終了」を示すＯＳＤ９３０が選択されると、コントローラー２１０は、撮影モードに移行し（Ｓ１４０）、使用者から撮影開始指示を受け付けるまで待機する。一方、図１１に示される画像を表示している際に、使用者により「調整」を示すＯＳＤ９２０が選択されると、コントローラー２１０は、調整モードに移行する。この調整モードは、左目用の画像、及び右目用の画像の何れか一方の画像が形成される位置を調整するための第１の調整モードと、第１のモードにおいて調整された一方の画像が形成される垂直方向の位置に対して、他方の画像が形成される垂直方向の位置を揃えるための第２のモードとを含む。本実施の形態では、第１のモードにおいて右目用の画像が形成される位置を調整し、第２のモードにおいて左目用の画像が形成される垂直方向の位置を調整する場合について説明するが、第１のモードにおいて左目用の画像が形成される位置を調整し、第２のモードにおいて右目用の画像が形成される垂直方向の位置を調整してもよい。 When the OSD 930 indicating “end” is selected by the user, the controller 210 shifts to a shooting mode (S140) and waits until a shooting start instruction is received from the user. On the other hand, when the OSD 920 indicating “adjustment” is selected by the user while the image shown in FIG. 11 is displayed, the controller 210 shifts to the adjustment mode. In this adjustment mode, the first adjustment mode for adjusting the position at which one of the image for the left eye and the image for the right eye is formed, and one image adjusted in the first mode are And a second mode for aligning the vertical position where the other image is formed with respect to the vertical position where it is formed. In this embodiment, the case where the position where the image for the right eye is formed is adjusted in the first mode and the position in the vertical direction where the image for the left eye is formed is adjusted in the second mode will be described. The position where the image for the left eye is formed may be adjusted in the first mode, and the position in the vertical direction where the image for the right eye is formed may be adjusted in the second mode.
　まず、コントローラー２１０は、第１の調整モードを実行する。すなわち、図１２（ａ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１５０）。なお、使用者は、３Ｄコンバージョンレンズ５００の位置を調整するときに、図１１に示される画像を認識した後、レンズキャップ５７０をデジタルビデオカメラ１００に取り付けるものとする。具体的には、コントローラー２１０は、垂直方向基準線９４０を２本表示するよう液晶モニタ２７０を制御する。また、コントローラー２１０は、ＣＣＤイメージセンサー１８０により撮像された左目用の画像９７０Ｌ及び右目用の画像９７０Ｒを表示するよう液晶モニタ２７０を制御する。また、コントローラー２１０は、「水平方向に調整して下さい。」というメッセージを表示するよう液晶モニタ２７０を制御する。使用者は、水平調整ダイヤル５４０を操作することにより、左目用の画像９７０Ｌと右目用の画像９７０Ｒを移動させ、これにより、これらの画像９７０Ｌと９７０Ｒの間に存在する領域である領域９５０を水平方向に移動できる。使用者は、領域９５０を２本の垂直方向基準線９４０の間に移動させることで、右目用レンズ６００及び左目用レンズ６２０の水平方向の位置を調整できる。また、デジタルビデオカメラ１００は、パターン５９０を撮像している。デジタルビデオカメラ１００は、コントラスト方式のＡＦによりパターン５９０に合焦させることができる。その結果、デジタルビデオカメラ１００は、基準線５８０にも合焦させることができる。 First, the controller 210 executes the first adjustment mode. That is, the liquid crystal monitor 270 is controlled to display the image shown in FIG. 12A (S150). It is assumed that the user attaches the lens cap 570 to the digital video camera 100 after recognizing the image shown in FIG. 11 when adjusting the position of the 3D conversion lens 500. Specifically, the controller 210 controls the liquid crystal monitor 270 to display two vertical reference lines 940. Further, the controller 210 controls the liquid crystal monitor 270 to display the left-eye image 970L and the right-eye image 970R captured by the CCD image sensor 180. In addition, the controller 210 controls the liquid crystal monitor 270 to display a message “Please adjust in the horizontal direction”. The user operates the horizontal adjustment dial 540 to move the image 970L for the left eye and the image 970R for the right eye, so that the region 950, which is an area existing between these images 970L and 970R, is leveled. Can move in the direction. The user can adjust the horizontal position of the right-eye lens 600 and the left-eye lens 620 by moving the region 950 between the two vertical reference lines 940. The digital video camera 100 captures the pattern 590. The digital video camera 100 can focus on the pattern 590 by contrast AF. As a result, the digital video camera 100 can also focus on the reference line 580.
　図１２（ａ）に示される画像を表示するよう液晶モニタ２７０を制御すると、コントローラー２１０は、使用者により「次へ」を示すＯＳＤ９９０がタッチされるか、「戻る」を示すＯＳＤ９８０がタッチされるまで待機する（Ｓ１６０）。 When the liquid crystal monitor 270 is controlled to display the image shown in FIG. 12A, the controller 210 touches the OSD 990 indicating “next” or the OSD 980 indicating “return” by the user. (S160).
　使用者により「戻る」を示すＯＳＤ９８０がタッチされると、コントローラー２１０は、再度図１１に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１２０に戻る）。一方、「次へ」を示すＯＳＤ９９０がタッチされると、コントローラー２１０は、図１２（ｂ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１７０）。具体的には、コントローラー２１０は、水平方向基準線９６０を２本表示するよう液晶モニタ２７０を制御する。また、コントローラー２１０は、ＣＣＤイメージセンサー１８０により撮像された画像のうち右目用の画像９７０Ｒのみを表示するよう液晶モニタ２７０を制御する。右目用の画像９７０Ｒのみを表示するのは、右目用の画像９７０Ｒと左目用の画像９７０Ｌの両方を表示すると、使用者がどちらの画像について調整すればよいかわからなくなる虞があるからである。また、コントローラー２１０は、「垂直方向に調整して下さい。」というメッセージを表示するよう液晶モニタ２７０を制御する。使用者は、第２垂直調整ダイヤル５６０を操作することにより、右目用の画像９７０Ｒを垂直方向に移動できる。使用者は、基準線５８０を２本の水平方向基準線９６０の間に移動させることで、右目用レンズ６００の垂直方向の位置を調整できる。 When the OSD 980 indicating “return” is touched by the user, the controller 210 controls the liquid crystal monitor 270 to display the image shown in FIG. 11 again (return to S120). On the other hand, when the OSD 990 indicating “next” is touched, the controller 210 controls the liquid crystal monitor 270 to display the image shown in FIG. 12B (S170). Specifically, the controller 210 controls the liquid crystal monitor 270 to display two horizontal reference lines 960. In addition, the controller 210 controls the liquid crystal monitor 270 so as to display only the right-eye image 970 </ b> R among images captured by the CCD image sensor 180. The reason why only the right-eye image 970R is displayed is that when both the right-eye image 970R and the left-eye image 970L are displayed, the user may not know which image should be adjusted. In addition, the controller 210 controls the liquid crystal monitor 270 to display a message “Please adjust in the vertical direction”. The user can move the image 970R for the right eye in the vertical direction by operating the second vertical adjustment dial 560. The user can adjust the vertical position of the right-eye lens 600 by moving the reference line 580 between the two horizontal reference lines 960.
　図１２（ｂ）に示される画像を表示するよう液晶モニタ２７０を制御すると、コントローラー２１０は、使用者により「次へ」を示すＯＳＤ９９０がタッチされるか、「戻る」を示すＯＳＤ９８０がタッチされるまで待機する（Ｓ１８０）。 When the LCD monitor 270 is controlled to display the image shown in FIG. 12B, the controller 210 touches the OSD 990 indicating “next” or the OSD 980 indicating “return” by the user. (S180).
　使用者により「戻る」を示すＯＳＤ９８０がタッチされると、コントローラー２１０は、再度図１２（ａ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１５０に戻る）。一方、「次へ」を示すＯＳＤ９９０がタッチされると、コントローラー２１０は、第２の調整モードを実行する。すなわち、コントローラー２１０は、図１２（ｃ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１９０）。具体的には、コントローラー２１０は、「レンズキャップを外してください。１．２ｍ～２．０ｍ離れた被写体を写してください」というメッセージを表示するよう液晶モニタ２７０を制御する。 When the OSD 980 indicating “return” is touched by the user, the controller 210 controls the liquid crystal monitor 270 again to display the image shown in FIG. 12A (return to S150). On the other hand, when the OSD 990 indicating “next” is touched, the controller 210 executes the second adjustment mode. That is, the controller 210 controls the liquid crystal monitor 270 to display the image shown in FIG. 12C (S190). Specifically, the controller 210 controls the liquid crystal monitor 270 to display a message “Please remove the lens cap. Please photograph a subject 1.2 to 2.0 m away”.
　図１２（ｃ）に示される画像を表示するよう液晶モニタ２７０を制御すると、コントローラー２１０は、使用者により「次へ」を示すＯＳＤ９９０がタッチされるか、「戻る」を示すＯＳＤ９８０がタッチされるまで待機する（Ｓ２００）。 When the liquid crystal monitor 270 is controlled to display the image shown in FIG. 12C, the controller 210 touches the OSD 990 indicating “next” or the OSD 980 indicating “return” by the user. (S200).
　使用者により「戻る」を示すＯＳＤ９８０がタッチされると、コントローラー２１０は、再度図１２（ｂ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１７０に戻る）。一方、「次へ」を示すＯＳＤ９９０がタッチされると、コントローラー２１０は、図１２（ｄ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ２１０）。具体的には、コントローラー２１０は、左目用の画像９９５Ｌと、右目用の画像９９５Ｒとを水平方向、及び垂直方向に液晶モニタ２７０の画素数に対応する大きさまで引き伸ばし、それぞれの画像を重畳して表示するよう液晶モニタ２７０を制御する。また、コントローラー２１０は、「画像の垂直方向のズレを調整して下さい。」というメッセージを表示するよう液晶モニタ２７０を制御する。使用者は、第２垂直調整ダイヤル５６０を操作することにより、左目用の画像９９５Ｌを垂直方向に移動できる。使用者は、左目用の画像９９５Ｌの垂直方向の位置を右目用の画像９９５Ｒの垂直方向の位置に移動させることで、左目用レンズ６２０の垂直方向の位置を調整できる。つまり、使用者は、このようにすることで、ＣＣＤイメージセンサー１８０に対する３Ｄコンバージョンレンズ５００の傾きにより生じる左目用画像９９５Ｌと右目用画像９９５Ｒとの垂直方向のズレを調整できる。３Ｄコンバージョンレンズ５００がデジタルビデオカメラ１００に対して傾いた状態で取り付けられると、撮像された画像も傾くこととなるが、この傾きは、使用者が画像を視認する際、左目用の画像と右目用の画像の上下方向のずれとなる。その結果、３Ｄ画像を視る使用者を疲れさせる。しかし、本実施形態では、上記のような構成を採用したことにより、このような不具合を防止することができる。 When the OSD 980 indicating “return” is touched by the user, the controller 210 controls the liquid crystal monitor 270 again to display the image shown in FIG. 12B (return to S170). On the other hand, when the OSD 990 indicating “next” is touched, the controller 210 controls the liquid crystal monitor 270 to display the image shown in FIG. 12D (S210). Specifically, the controller 210 extends the image 995L for the left eye and the image 995R for the right eye in the horizontal direction and the vertical direction to a size corresponding to the number of pixels of the liquid crystal monitor 270, and superimposes the respective images. The liquid crystal monitor 270 is controlled to display. In addition, the controller 210 controls the liquid crystal monitor 270 to display a message “Please adjust the vertical displacement of the image.” The user can move the image 995L for the left eye in the vertical direction by operating the second vertical adjustment dial 560. The user can adjust the vertical position of the left-eye lens 620 by moving the vertical position of the left-eye image 995L to the vertical position of the right-eye image 995R. That is, the user can adjust the vertical shift between the left-eye image 995L and the right-eye image 995R, which are caused by the inclination of the 3D conversion lens 500 with respect to the CCD image sensor 180, in this way. When the 3D conversion lens 500 is attached to the digital video camera 100 in a tilted state, the captured image is also tilted. This tilt causes the left eye image and the right eye to be viewed when the user visually recognizes the image. This is a vertical displacement of the image for use. As a result, the user who views the 3D image is tired. However, in the present embodiment, such a problem can be prevented by adopting the above configuration.
　図１２（ｄ）に示される画像を表示するよう液晶モニタ２７０を制御すると、コントローラー２１０は、使用者により「次へ」を示すＯＳＤ９９０がタッチされるか、「戻る」を示すＯＳＤ９８０がタッチされるまで待機する（Ｓ２２０）。 When the LCD monitor 270 is controlled to display the image shown in FIG. 12D, the controller 210 touches the OSD 990 indicating “next” or the OSD 980 indicating “return” by the user. (S220).
　使用者により「戻る」を示すＯＳＤ９８０がタッチされると、コントローラー２１０は、再度図１２（ｃ）に示される画像を表示するよう液晶モニタ２７０を制御する（Ｓ１９０）。一方、「次へ」を示すＯＳＤ９９０がタッチされると、コントローラー２１０は、撮影モードに移行するようデジタルビデオカメラ１００全体を制御する（Ｓ２３０）。 When the OSD 980 indicating “return” is touched by the user, the controller 210 controls the liquid crystal monitor 270 to display the image shown in FIG. 12C again (S190). On the other hand, when the OSD 990 indicating “next” is touched, the controller 210 controls the entire digital video camera 100 to shift to the shooting mode (S230).
１－６－２　電源ＯＦＦ時の動作
　撮影モードに移行後、コントローラー２１０は、使用者によりデジタルビデオカメラ１００の電源をＯＦＦする指示がなされたかを判断する（Ｓ２４０）。使用者により電源をＯＦＦする指示がなされたと判断すると、コントローラー２１０は、デジタルビデオカメラ１００に３Ｄコンバージョンレンズ５００が取り付けられているか否かを判断する（Ｓ２５０）。３Ｄコンバージョンレンズ５００が取り付けられていないと判断すると、コントローラー２１０は、電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていない旨を示す情報（例えば、取り付けられていないことを示すフラグ）を内部メモリ２８０に記録する（Ｓ２６０）。一方、３Ｄコンバージョンレンズ５００が取り付けられていると判断すると、コントローラー２１０は、電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられている旨を示す情報（例えば、取り付けられていることを示すフラグ）を内部メモリ２８０に記録する（Ｓ２７０）。電源ＯＦＦ時の３Ｄコンバージョンレンズ５００の着脱状態に関する情報を内部メモリ２８０に記録すると、コントローラー２１０は、電源をＯＦＦするようデジタルビデオカメラ１００全体を制御する（Ｓ２８０）。 1-6-2 Operation when Power is Off After shifting to the shooting mode, the controller 210 determines whether the user has instructed to turn off the power of the digital video camera 100 (S240). If it is determined that the user has instructed to turn off the power, the controller 210 determines whether or not the 3D conversion lens 500 is attached to the digital video camera 100 (S250). If the controller 210 determines that the 3D conversion lens 500 is not attached, the controller 210 sends information indicating that the 3D conversion lens 500 is not attached when the power is turned off (for example, a flag indicating that the 3D conversion lens 500 is not attached) to the internal memory 280. Record (S260). On the other hand, when determining that the 3D conversion lens 500 is attached, the controller 210 stores information indicating that the 3D conversion lens 500 is attached when the power is turned off (for example, a flag indicating that the 3D conversion lens 500 is attached) in the internal memory. It is recorded in 280 (S270). When information regarding the attachment / detachment state of the 3D conversion lens 500 when the power is turned off is recorded in the internal memory 280, the controller 210 controls the entire digital video camera 100 to turn off the power (S280).
１－６－３．電源ＯＮ時の動作
　デジタルビデオカメラ１００における電源ＯＮ時の動作について図１３を用いて説明する。図１３は、デジタルビデオカメラ１００における電源ＯＮ時の動作を説明するためのフローチャートである。 1-6-3. Operation when the power is turned on The operation of the digital video camera 100 when the power is turned on will be described with reference to FIG. FIG. 13 is a flowchart for explaining the operation of the digital video camera 100 when the power is turned on.
　使用者による電源ＯＮの操作を受け付けると（Ｓ３００）、コントローラー２１０は検出スイッチ８００からの検出信号に基づき、電源ＯＮ時に３Ｄコンバージョンレンズ５００が取り付けられているか否かを判断する（Ｓ３１０）。３Ｄコンバージョンレンズ５００が取り付けられていないと判断すると、コントローラー２１０は、２Ｄ撮影モードに移行するようデジタルビデオカメラ１００全体を制御する（Ｓ３２０）。一方、３Ｄコンバージョンレンズ５００が取り付けられていると判断すると、コントローラー２１０は、内部メモリ２８０内に前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた旨の情報が記憶されているか否かを判断する（Ｓ３３０）。 When accepting an operation to turn on the power by the user (S300), the controller 210 determines whether or not the 3D conversion lens 500 is attached when the power is turned on based on the detection signal from the detection switch 800 (S310). If it is determined that the 3D conversion lens 500 is not attached, the controller 210 controls the entire digital video camera 100 to shift to the 2D shooting mode (S320). On the other hand, when determining that the 3D conversion lens 500 is attached, the controller 210 determines whether or not information indicating that the 3D conversion lens 500 was attached when the power was last turned off is stored in the internal memory 280. (S330).
　電源ＯＮ時に３Ｄコンバージョンレンズ５００が取り付けられている状態において、この電源ＯＮの前の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた旨の情報が記憶されていると判断すると、コントローラー２１０は、警告を表示する（Ｓ３４５）。図１４は、電源ＯＦＦ時及びこの電源ＯＦＦの後の電源ＯＮ時の両方において３Ｄコンバージョンレンズ５００が取り付けられていることが検出されたときの液晶モニタ２７０の表示内容を説明した図である。具体的には、「前回使用時と今回使用時との間に３Ｄコンバージョンレンズ５００を取り外した場合は、３Ｄコンバージョンレンズ５００の調整を行ってください。」と調整を促す警告表示を行う。内部メモリ２８０内に前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた旨の情報が記憶されており、かつ今回の電源ＯＮ時に３Ｄコンバージョンレンズ５００が取り付けられていると判断された場合であっても、電源ＯＦＦ状態の間に３Ｄコンバージョンレンズ５００が一旦取り外され、その後再度取り付けられている可能性がある。このような場合、３Ｄコンバージョンレンズ５００の取り付け状態が適切でない可能性がある。そこで、電源ＯＦＦ時及びこの電源ＯＦＦの後の電源ＯＮ時の両方において３Ｄコンバージョンレンズ５００が取り付けられていることが検出された場合であっても、３Ｄコンバージョンレンズ５００の調整を促す警告表示を行う。 If the controller 210 determines that information indicating that the 3D conversion lens 500 was attached when the power was turned off before the power was turned on in a state where the 3D conversion lens 500 was attached when the power was turned on, the controller 210 warns. Is displayed (S345). FIG. 14 is a diagram illustrating the display content of the liquid crystal monitor 270 when it is detected that the 3D conversion lens 500 is attached both when the power is turned off and when the power is turned on after the power is turned off. Specifically, a warning display for prompting the adjustment is displayed, “If the 3D conversion lens 500 is removed between the previous use and the current use, please adjust the 3D conversion lens 500.” This is a case where the internal memory 280 stores information indicating that the 3D conversion lens 500 was attached when the power was turned off the last time, and it was determined that the 3D conversion lens 500 was attached when the power was turned on this time. However, there is a possibility that the 3D conversion lens 500 is once removed during the power-off state and then attached again. In such a case, the attached state of the 3D conversion lens 500 may not be appropriate. Therefore, even when it is detected that the 3D conversion lens 500 is attached both when the power is turned off and when the power is turned on after the power is turned off, a warning display prompting adjustment of the 3D conversion lens 500 is performed. .
　警告表示から例えば所定時間経過後、コントローラー２１０は、３Ｄの撮影モードに移行するようデジタルビデオカメラ１００全体を制御する（Ｓ３５０）。一方、ステップＳ３３０において、３Ｄコンバージョンレンズ５００が取り付けられていなかった旨の情報が記憶されていると判断すると、コントローラー２１０は、図９ＡにおけるステップＳ１００に移行し（Ｓ３４０）、以後、図９Ａのフローチャートに示す処理を行う。なお、ステップＳ３４５とステップＳ３５０との間に使用者による調整要否の判定を行うステップを設け、使用者により調整要の判定がなされた場合は、ステップＳ１００に移行して以後の処理を行い、一方、使用者により調整不要の判定がなされた場合は、ステップＳ３５０に移行するようにしてもよい。 For example, after a predetermined time has elapsed from the warning display, the controller 210 controls the entire digital video camera 100 to shift to the 3D shooting mode (S350). On the other hand, if it is determined in step S330 that information indicating that the 3D conversion lens 500 has not been attached is stored, the controller 210 proceeds to step S100 in FIG. 9A (S340), and thereafter the flowchart of FIG. 9A. The process shown in is performed. It should be noted that a step for determining whether or not adjustment is necessary by the user is provided between step S345 and step S350, and if the necessity for adjustment is determined by the user, the process proceeds to step S100 and the subsequent processing is performed. On the other hand, if the user determines that adjustment is unnecessary, the process may proceed to step S350.
１－７．まとめ
　このように本実施の形態にかかるデジタルビデオカメラ１００は、３Ｄコンバージョンレンズ５００内の光学系の調整を行う際、具体的には左目用の画像９９５Ｌの垂直方向の結像位置と右目用の画像９９５Ｒの垂直方向の結像位置とのズレを使用者に調整させる際、図１２（ｄ）に示すように、ＣＣＤイメージセンサー１８０により撮像された左目用の画像９９５Ｌと右目用の画像９９５Ｒとを重畳して液晶モニタ２７０に表示する。これにより、使用者は、左目用の画像９９５Ｌの垂直方向の結像位置と右目用の画像９９５Ｒの垂直方向の結像位置とのズレを視覚的に認識できる。したがって、３Ｄコンバージョンレンズ５００の取り付け状態の調整を高精度に行うことができる。 1-7. Summary As described above, when the digital video camera 100 according to the present embodiment adjusts the optical system in the 3D conversion lens 500, specifically, the image formation position in the vertical direction of the image 995L for the left eye and the image for the right eye are specifically described. When the user adjusts the deviation of the image 995R from the vertical imaging position, as shown in FIG. 12D, the left-eye image 995L and the right-eye image 995R captured by the CCD image sensor 180 are displayed. Are superimposed and displayed on the liquid crystal monitor 270. As a result, the user can visually recognize a deviation between the vertical image formation position of the left-eye image 995L and the vertical image formation position of the right-eye image 995R. Therefore, the attachment state of the 3D conversion lens 500 can be adjusted with high accuracy.
　また、本実施の形態にかかるデジタルビデオカメラ１００は、図１２（ａ）、図１２（ｂ）に示すように、一方の画像の結像位置を使用者に確定調整させた後に、他方の画像の結像位置を使用者に確定させる。これにより、使用者は、左目用の画像９９５Ｌの結像位置と右目用の画像９９５Ｒの結像位置とのズレを容易に調整できる。 In addition, as shown in FIGS. 12A and 12B, the digital video camera 100 according to the present embodiment allows the user to confirm and adjust the imaging position of one image, and then the other image. The user determines the image forming position. Accordingly, the user can easily adjust the deviation between the imaging position of the left-eye image 995L and the imaging position of the right-eye image 995R.
　また、本実施の形態にかかるデジタルビデオカメラ１００は、図１１に示すように、一方の画像の結像位置を使用者に確定させる際に、レンズキャップ５７０を取り付けるよう促すメッセージを液晶モニタ２７０に表示する。また、デジタルビデオカメラ１００は、他方の画像の結像位置を既に結像位置を確定した画像の結像位置との関係で使用者に調整させる際に、図１２（ｃ）に示すように、レンズキャップ５７０を取り外すよう促すメッセージを液晶モニタ２７０に表示する。これは、以下の理由による。仮に３Ｄコンバージョンレンズ５００がＣＣＤイメージセンサー１８０に対して傾いていたとすると、レンズキャップ５７０も３Ｄコンバージョンレンズ５００と共に、ＣＣＤイメージセンサー１８０に対して傾いてしまう。この傾いた状態では、ＣＣＤイメージセンサー１８０で撮像された左右の三角形のパターン５９０の垂直方向の位置にズレが生じる。このようにずれた状態において、左右の三角形のパターン５９０の垂直方向のズレがなくなるように調整すると、レンズキャップ５７０を取り外した状態で被写体を撮影したときに、被写体の垂直方向の位置がずれることとなる。したがって、ＣＣＤイメージセンサー１８０に対する３Ｄコンバージョンレンズ５００の傾きにより生じる左目用画像と右目用画像との垂直方向のズレの調整は、レンズキャップ５７０を取り外した状態で行う必要がある。そこで、ＣＣＤイメージセンサー１８０に対する３Ｄコンバージョンレンズ５００の傾きにより生じる左目用画像と右目用画像との垂直方向のズレを調整する際には、レンズキャップ５７０を取り外すように使用者に促す。これにより、上記のように３Ｄコンバージョンレンズ５００がＣＣＤイメージセンサー１８０に対して傾いてしまうという不具合を防止しつつ、左目用画像と右目用画像との垂直方向のズレを使用者に正確に調整させることができる。これにより、使用者は、一方の画像の結像位置の確定を容易に行うことができ、かつ、他方の画像の結像位置を既に結像位置を確定した画像の結像位置との関係で容易に調整できる。 Further, as shown in FIG. 11, the digital video camera 100 according to the present embodiment displays a message prompting the user to attach the lens cap 570 to the liquid crystal monitor 270 when the user determines the image formation position of one image. indicate. In addition, when the digital video camera 100 causes the user to adjust the imaging position of the other image in relation to the imaging position of the image whose imaging position has already been determined, as shown in FIG. A message prompting the user to remove the lens cap 570 is displayed on the liquid crystal monitor 270. This is due to the following reason. If the 3D conversion lens 500 is inclined with respect to the CCD image sensor 180, the lens cap 570 is also inclined with respect to the CCD image sensor 180 together with the 3D conversion lens 500. In this inclined state, a deviation occurs in the vertical position of the left and right triangular patterns 590 captured by the CCD image sensor 180. If the right and left triangular pattern 590 is adjusted so that there is no vertical shift in such a shifted state, the vertical position of the subject is shifted when the subject is photographed with the lens cap 570 removed. It becomes. Therefore, it is necessary to adjust the vertical shift between the left-eye image and the right-eye image caused by the inclination of the 3D conversion lens 500 with respect to the CCD image sensor 180 with the lens cap 570 removed. Therefore, when adjusting the vertical shift between the left-eye image and the right-eye image caused by the tilt of the 3D conversion lens 500 with respect to the CCD image sensor 180, the user is prompted to remove the lens cap 570. As a result, the user can accurately adjust the vertical shift between the left-eye image and the right-eye image while preventing the problem that the 3D conversion lens 500 is inclined with respect to the CCD image sensor 180 as described above. be able to. As a result, the user can easily determine the imaging position of one image, and the imaging position of the other image is related to the imaging position of the image whose imaging position has already been determined. Easy to adjust.
　また、本実施の形態にかかるデジタルビデオカメラ１００は、電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていたか否かを示す情報を内部メモリ２８０に記憶する。これにより、デジタルビデオカメラ１００は、電源ＯＮ時に前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていたか否かを認識できる。その結果、前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた場合には図９ＡにおけるステップＳ１００からの制御、すなわち３Ｄコンバージョンレンズの取り付けが検出された場合の制御を行わない。これは、前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた場合には、既に３Ｄコンバージョンレンズ５００の調整が完了している場合が多いからである。既に３Ｄコンバージョンレンズ５００の調整が完了しているにも関わらず、上記３Ｄコンバージョンレンズの取り付けが検出された場合の制御が行われると使用者にとって煩わしい。そこで、本実施の形態にかかるデジタルビデオカメラ１００は、前回の電源ＯＦＦ時に３Ｄコンバージョンレンズ５００が取り付けられていた場合には上記３Ｄコンバージョンレンズの取り付けが検出された場合の制御を行わないこととしている。 Also, the digital video camera 100 according to the present embodiment stores information indicating whether or not the 3D conversion lens 500 is attached when the power is turned off in the internal memory 280. Thereby, the digital video camera 100 can recognize whether or not the 3D conversion lens 500 was attached when the power was turned on the last time when the power was turned on. As a result, if the 3D conversion lens 500 was attached when the power was turned off last time, the control from step S100 in FIG. 9A, that is, the control when the attachment of the 3D conversion lens is detected is not performed. This is because the adjustment of the 3D conversion lens 500 has already been completed in many cases when the 3D conversion lens 500 was attached when the power was turned off last time. Although the adjustment of the 3D conversion lens 500 has already been completed, it is troublesome for the user to perform the control when the attachment of the 3D conversion lens is detected. Therefore, the digital video camera 100 according to the present embodiment does not perform control when the attachment of the 3D conversion lens is detected when the 3D conversion lens 500 is attached when the power is turned off last time. .
２．実施の形態２
　本発明をデジタルビデオカメラに適用した実施の形態２について図面を用いて説明する。なお、実施の形態１と共通の部分については説明を省略する。実施の形態２にかかるデジタルビデオカメラは、実施の形態１にかかるデジタルビデオカメラにおける図１２（ｄ）の表示（左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際の表示）にかかる部分が異なる。以下、その点について説明する。 2. Embodiment 2
Embodiment 2 in which the present invention is applied to a digital video camera will be described with reference to the drawings. Note that description of portions common to the first embodiment is omitted. The digital video camera according to the second embodiment adjusts the display (the vertical position of the left-eye image and the vertical position of the right-eye image) of the digital video camera according to the first embodiment as shown in FIG. The display area is different. This will be described below.
　本実施の形態における左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際の液晶モニタ２７０の表示について図１５を用いて説明する。図１５は、左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際に液晶モニタ２７０に表示される画像を説明した図である。 The display on the liquid crystal monitor 270 when adjusting the vertical position of the left-eye image and the vertical position of the right-eye image in the present embodiment will be described with reference to FIG. FIG. 15 is a diagram illustrating an image displayed on the liquid crystal monitor 270 when the vertical position of the left-eye image and the vertical position of the right-eye image are adjusted.
　本実施の形態にかかるデジタルビデオカメラ１００は、左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを使用者に揃えさせる際に、左目用画像を液晶モニタ２７０の画素数に対応する大きさに引き伸ばした画像と、右目用画像を液晶モニタ２７０の画素数に対応する大きさに引き伸ばした画像とを時間的に交互に液晶モニタ２７０に表示する。例えば、本実施の形態においては、左目用画像と右目用画像とを１／３０秒おきに交互に表示する。 When the digital video camera 100 according to the present embodiment aligns the vertical position of the left-eye image and the vertical position of the right-eye image to the user, the left-eye image is set to the number of pixels of the liquid crystal monitor 270. The image enlarged to the corresponding size and the image obtained by extending the right-eye image to the size corresponding to the number of pixels of the liquid crystal monitor 270 are alternately displayed on the liquid crystal monitor 270 in terms of time. For example, in the present embodiment, the left-eye image and the right-eye image are alternately displayed every 1/30 seconds.
　使用者は、実施の形態１と同様、第２垂直調整ダイヤル５６０を操作することにより、左目用の画像を垂直方向に移動できる。使用者は、左目用の画像の垂直方向の位置を右目用の画像の垂直方向の位置に移動させることで、左目用レンズ６２０の垂直方向の位置を調整できる。これにより、使用者は、左目用の画像の結像位置と右目用の画像の結像位置とのズレを容易に調整できる。 As with the first embodiment, the user can move the image for the left eye in the vertical direction by operating the second vertical adjustment dial 560. The user can adjust the vertical position of the left-eye lens 620 by moving the vertical position of the left-eye image to the vertical position of the right-eye image. Accordingly, the user can easily adjust the deviation between the image formation position of the image for the left eye and the image formation position of the image for the right eye.
３．実施の形態３
　本発明をデジタルビデオカメラに適用した実施の形態３について図面を用いて説明する。なお、実施の形態１と共通の部分については説明を省略する。実施の形態３にかかるデジタルビデオカメラは、実施の形態１にかかるデジタルビデオカメラにおける図１２（ｄ）の表示（左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際の表示）にかかる部分が異なる。以下、その点について説明する。 3. Embodiment 3
Embodiment 3 in which the present invention is applied to a digital video camera will be described with reference to the drawings. Note that description of portions common to the first embodiment is omitted. The digital video camera according to the third embodiment adjusts the display in FIG. 12D of the digital video camera according to the first embodiment (the vertical position of the left-eye image and the vertical position of the right-eye image). The display area is different. This will be described below.
　本実施の形態における左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際の液晶モニタ２７０の表示について図１６を用いて説明する。図１６は、左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを調整する際の液晶モニタ２７０の表示の模式図である。 The display on the liquid crystal monitor 270 when adjusting the vertical position of the left-eye image and the vertical position of the right-eye image in the present embodiment will be described with reference to FIG. FIG. 16 is a schematic diagram of display on the liquid crystal monitor 270 when adjusting the vertical position of the left-eye image and the vertical position of the right-eye image.
　本実施の形態にかかるデジタルビデオカメラ１００は、左目用画像の垂直方向の位置と右目用画像の垂直方向の位置とを使用者に揃えさせる際に、左目用の画像を垂直方向に引き伸ばした画像９９７Ｌと右目用の画像を垂直方向に引き伸ばした画像９９７Ｒとを左右に並べて同時に液晶モニタ２７０に表示する。 The digital video camera 100 according to the present embodiment is an image obtained by stretching the left-eye image in the vertical direction when aligning the vertical position of the left-eye image and the vertical position of the right-eye image to the user. 997L and an image 997R obtained by enlarging the right-eye image in the vertical direction are displayed side by side on the liquid crystal monitor 270 at the same time.
　使用者は、実施の形態１同様、第１垂直調整ダイヤル５５０を操作することにより、左目用の画像９９７Ｌを垂直方向に移動できる。使用者は、左目用の画像９９７Ｌの垂直方向の位置を右目用の画像９９７Ｒの垂直方向の位置に移動させることで、左目用レンズ６２０の垂直方向の位置を調整できる。これにより、使用者は、左目用の画像９９７Ｌの結像位置と右目用の画像９９７Ｒの結像位置とを容易に調整できる。 As in the first embodiment, the user can move the image 997L for the left eye in the vertical direction by operating the first vertical adjustment dial 550. The user can adjust the vertical position of the left-eye lens 620 by moving the vertical position of the left-eye image 997L to the vertical position of the right-eye image 997R. Accordingly, the user can easily adjust the imaging position of the image 997L for the left eye and the imaging position of the image 997R for the right eye.
　実施の形態３では、左目用の画像及び右目用の画像をそれぞれ垂直方向に引き伸ばしているので、垂直方向の位置の調整を行い易くなるとともに、調整精度を確保しやすくなる。 In Embodiment 3, since the image for the left eye and the image for the right eye are each stretched in the vertical direction, it is easy to adjust the position in the vertical direction and to ensure adjustment accuracy.
４．他の実施の形態
　以上、本発明の実施の形態として、実施の形態１～３を説明した。しかし、本発明は、これらには限定されない。以下、本発明の他の実施の形態を説明する。
4). Other Embodiments The first to third embodiments have been described above as the embodiments of the present invention. However, the present invention is not limited to these. Hereinafter, other embodiments of the present invention will be described.
　本実施の形態にかかるデジタルビデオカメラ１００の光学系及び駆動系は、図８に示すものに限定されない。例えば、図８では３群構成の光学系を例示しているが、他の群構成のレンズ構成としてもよい。また、それぞれのレンズは、１つのレンズで構成してもよく、複数のレンズから構成されるレンズ群として構成してもよい。 The optical system and drive system of the digital video camera 100 according to the present embodiment are not limited to those shown in FIG. For example, FIG. 8 illustrates an optical system having a three-group configuration, but a lens configuration having another group configuration may be used. In addition, each lens may be composed of one lens or a lens group composed of a plurality of lenses.
　また、実施の形態１～３では、撮像手段として、ＣＣＤイメージセンサー１８０を例示したが、本発明はこれに限定されない。例えば、撮像手段をＣＭＯＳイメージセンサーで構成してもよく、ＮＭＯＳイメージセンサーで構成してもよい。 In the first to third embodiments, the CCD image sensor 180 is exemplified as the imaging means, but the present invention is not limited to this. For example, the imaging means may be configured with a CMOS image sensor or an NMOS image sensor.
　また、実施の形態１～３では、左目用画像と右目用画像のＣＣＤイメージセンサー１８０における水平方向の結像位置の調整、及び右目用画像のＣＣＤイメージセンサー１８０における垂直方向の結像位置の調整をレンズキャップ５７０を取り付けた状態で使用者に行わせている。しかしながら、必ずしもこのような構成には限定されない。レンズキャップ５７０を取り付けていない状態で、左目用画像と右目用画像のＣＣＤイメージセンサー１８０における水平方向の結像位置の調整、及び右目用画像のＣＣＤイメージセンサー１８０における垂直方向の結像位置の調整を使用者に行わせるような構成であってもよい。 In the first to third embodiments, the horizontal image formation position of the left-eye image and the right-eye image in the CCD image sensor 180 is adjusted, and the vertical image formation position of the right-eye image in the CCD image sensor 180 is adjusted. Is performed by the user with the lens cap 570 attached. However, it is not necessarily limited to such a configuration. When the lens cap 570 is not attached, the horizontal image formation position of the left-eye image and the right-eye image in the CCD image sensor 180 and the vertical image formation position of the right-eye image in the CCD image sensor 180 are adjusted. The configuration may be such that the user performs the above.
　また、実施の形態１では、３Ｄコンバージョンレンズ５００の取付状態の調整時に左目用画像と右目用画像とを重畳した画像を表示するよう液晶モニタ２７０を制御した。しかしながら、必ずしもこのような構成には限定されない。例えば、３Ｄ画像を再生し、液晶モニタ２７０に表示させる際に、左目用画像と右目用画像とを重畳した画像を表示するよう液晶モニタ２７０を制御してもよい。これにより、左目用画像と右目用画像との視差がどの程度であるかを２Ｄ対応の液晶モニタ上で使用者に認識させることができる。 In Embodiment 1, the liquid crystal monitor 270 is controlled to display an image in which the left-eye image and the right-eye image are superimposed when adjusting the mounting state of the 3D conversion lens 500. However, it is not necessarily limited to such a configuration. For example, when a 3D image is reproduced and displayed on the liquid crystal monitor 270, the liquid crystal monitor 270 may be controlled to display an image in which a left-eye image and a right-eye image are superimposed. This allows the user to recognize the degree of parallax between the left-eye image and the right-eye image on the 2D-compatible liquid crystal monitor.
　本実施形態では、上述のように、３Ｄコンバージョンレンズ５００の取付状態の調整時に液晶モニタ２７０に左目用画像と右目用画像とを重畳（合成）した画像を表示する。この重畳（合成）の態様の一例として図１２（ｄ）を示したが、２つの画像が同時に表示され、液晶モニタ２７０上において左目用画像及び右目用画像の垂直方向の位置がそれぞれ認識可能である限り、如何なる態様であってもよい。例えば、半透明な左目用画像と右目用画像を重ねて表示してもよい。また、不透明な左目用画像と右目用画像を重ねて表示してもよい。なお、左目用画像と右目用画像の重畳は、両画像を合成することにより行うこともできる。 In the present embodiment, as described above, an image in which the left-eye image and the right-eye image are superimposed (synthesized) is displayed on the liquid crystal monitor 270 when the mounting state of the 3D conversion lens 500 is adjusted. Although FIG. 12D is shown as an example of this superposition (combination) mode, two images are displayed simultaneously, and the vertical positions of the left-eye image and the right-eye image can be recognized on the liquid crystal monitor 270, respectively. As long as it is, any mode may be used. For example, a semi-transparent left eye image and right eye image may be displayed in an overlapping manner. Further, an opaque left-eye image and right-eye image may be displayed in an overlapping manner. Note that the superposition of the left-eye image and the right-eye image can also be performed by combining both images.
　本発明は、デジタルビデオカメラやデジタルスチルカメラ等の撮像装置に適用できる。 The present invention can be applied to an imaging apparatus such as a digital video camera or a digital still camera.
